"At Scope Photonics in Ontario, Canada, they want to create lossless zoom for all kinds of images, which means any photo enjoying a close-up will remain consistently sharp. Chief executive Holden Beggs and his team have been working on a type of technology harnessing liquid crystals, made popular by liquid-crystal display (LCD) screens found in living rooms and retail displays across the world.
Scope Photonics has found a way to make liquid crystals "spin like tops" and reorganise themselves based on how light moves through them. The effect is to mimic a zoom lens system. So instead of a series of lenses, Scope's system can zoom in and out with just the one lens.
The International Runner Up for the 2020 James Dyson Award, Scope is prototyping the lens technology on medical devices first, and aims to bring these lenses to smartphone cameras in three years. In virtual reality especially, those companies want to reduce the bulkiness of those headsets, and that's what we want to do, and it's what we do now with our very thin lenses.
In Utah, a group of researchers have developed a lens a hundred times lighter and a thousand times thinner than the iPhone 11's lenses. Rajesh Menon, associate professor in electrical and computer engineering at Utah University, says a common problem for current phone cameras is spotting out-of-focus reds and blues and correcting - that often requires an additional lens."
